Maya is playing a trivia game with multiple choice questions. Each question has 222 correct answers among 555 answer choices. Maya has no idea what the answers to a certain question are, so she needs to choose two different answers at random. What is the probability that maya's first guess is correct and her second guess is incorrect? round your answer to two decimal places.

Answers

Answer 1

The probability that maya's first guess is correct and her second guess is incorrect is 0.24

From the question given above, the following data were obtained:

Correct answer (C) = 222Total answer = 555Incorrect answer (I) = 555 – 222 = 333

Next, we shall determine the probability that her 1st guess is correct.

Correct answer, nC = 222Total answer, nS= 555Probability of correct answer, P(C) =?

P(C) = nC / nS

P(C) = 222 / 555

Next, we shall determine the probability that her 2nd guess is incorrect

Incorrect answer, nI = 333Total answer, nS = 554Probability of incorrect answer, P(I) =?

P(I) = nI / nS

P(I) = 333 / 554

Finally, we shall determine the probability that her first guess is correct and her second guess is incorrect.

Probability of correct answer, P(C) = 222 / 555Probability of incorrect answer, P(I) = 333 / 554Probability of 1st correct and 2nd incorrect, P(C n I) =?

P(C n I) = P(C) × P(I)

P(C n I) = (222 / 555) × (333 / 554)

P(C n I) = 0.24

a player pays $15 to play a game in which a chip is randomly selected from a bag of chips. the bag contains 10 red chips, 4 blue chips, and 6 yellow chips. the player wins $5 if a red chip is selected, $10 if a blue chip is selected, and $20 if a yellow chip is selected. let the random variable x represent the amount won from the selection of the chip, and let the random variable w represent the total amount won, where w=x−15. what is the mean of w ?

Answers

The mean of w which represents the total amount won where w = x + 15 is;

w = -$4.5

We are given;

Winnings if a red chip is selected; x₁ = $5.

Now, there are 10 red chips in a bag of 20 chips.

Thus, the probability of this outcome is:

p₁ = 10/20

p₁ = 1/2

Winnings if a blue chip is selected; x₂ = $10

Now, there are 4 blue chips in a bag of 20 chips.

Thus, the probability of this outcome is:

p₂ = 4/20

p₂ = 1/5

Winnings if a yellow chip is selected; x₃ = $20

Now, there are 6 blue chips in a bag of 20 chips.

Thus, the probability of this outcome is:

p₃ = 6/20

p₃ = 3/10

Finally, the expected value is:

E(X) = 5(¹/₂) + 10(¹/₅) + 20(³/₁₀)

E(X) = $10.5

We are told that w = x - 15

where x is the amount won from selection of chip which is E(X) = $10.5

Thus;

w = 10.5 - 15

w = -$4.5
